To-all it may concern:

Be it known thatL JoHN' C. BRooKs, a citis zen-of-theUnited States,residing at Paterson,

in the county of Pas'saic and State of NewJer- .sey, have invented anImprovement in Looms, v of whichthe following des'cription, ineonnection with theaccomp'anying drawings, is a the drawings.

cially to means for detecting the occurrence of a float inthe,warp.and"for immediately stopping the 100m upon theo ccurrence'ofpick-outs, as they are termed. r In my present invention the stopping othe loom is accomplished by means of a feeler which cooperates with afeeler-jcontroller car 7 ried by the shuttle to knock ofirtheshipperlever whenever a float occurs, I

In the best form of my- 1I1Vent1Qn-n0W known to me the feelervis pivotedto the lay,

and the shuttle is provided with a recess or opening into and out ofwhich oneend of the feeler plays, said feeler being givenits'movementrelative-to the shuttle by or through the 'movementof the lay. Carriedbypthe' shuttle is'a feeler-controller which is normally held in itsinoperative position out of the. path'of the feeler by means of afloat-detecting lever.

Suitable automatically-operative means, such as springs, are employedtothrow the feelercontroller into its operative position, which is inthepatheof thefeele'r, whenever the float-detecting lever releases saidfecler-controller by or through the occurrence of a float. As soon asthe 'feeler-controller is thus thrown'xintg') its operative positionacross theopening in the shuttle said feelerbontrolleiv cooperates withthe feeler upon the forward b'eatof the lay to knock-oil the shipper,and fthus stop the loom. ln the drawings, Figure 1 is a side View of aportion-of the 100m having-my improve ments applied thereto, the lay'andshuttle being shown in section to better illustrate my invention. Fig. 2is a section of a shuttle having my improvements applied thereto on'Loom;

substantially the use Fig.3.- Fig, 3- is :1

itop plan view of Fig-. 2.

The breast-beam of, he loom 3, the shippcr-- shuttle is designated by Sand may be of any suitable-or usual type,"said shuttle having at oneend-an opening or recess 9, which comes .inalinement with'the opening 8in the shuttle-box when said shuttle is properlyboxed.

' Mounted inasuitable recess in the side ot' the shuttle and arrangedto: be moved back and forth across the mouth of the recess 9' is afeelerecontroller 10, which cooperates with the feeler upon theoccurrence of a float to stop the loom. As herein illustrated, said*zt'eeler-controller comprises a sliding member mounted in a suitablerecess 11 in the-wall of the shuttle, said feeler-controllerbein'gguided in any'suitable Way, as by means of thepins 12, carried by" theshuttle, which extend through the'slot 13 in said feeler-controllciz-Said, feeler controller is provided with a shoulder; 14, adapted to beengaged by the "nose 150i a float-detecting lever;16,,s'aid le-' verbeing pivoted inthe'recess 11 of the shut- I :tleand having one end 17thereof projecting above the shuttle-wall, as best seen in Fig. 2. w-Thefloat-detecting lever is held in operative position, or that shown inFig..-2,"in any suit able way, as by a spring 18.

Suitable automatically operative means,

i such asa spring 19, is employed to throw the feeler-controller into.its operative position whenever it isreleased, by the float-detectinglever, I." V} i Y i The parts are normallyin-the position shown in Fig.2' that is, the 'feeler 4 controller; is withdrawn from acrossthe recess'9 and is held inits retracted or inoperative position by thefloa't-detectir lever 16.

,Whenevera; float occurs in the warp and the. shuttle makes an overshot,the warpthreads will by their engagement with the end'l'? of thefloat-detectinglever depress said the shuttle-box.

end, and thus release the fecler-controller. Thereupon the spring 19comes into play to throw said feeler-controller forward and over theopening 9 in the shuttle. W hen the feelercontroller is in thisposition, which is its'operative position, it cooperates with the feelerto stop the loom, as will be presently described.

Iivoted to the loom-frame is a hanger 20, which is suitably connected toone arm of the knock-ofi' lever 21. Said hanger 20 also carries asuitable buffer 22, which stands in the path of movement of the buntingend 23 of the feeler.

When the loom is running normally, the fceler-conlroller 10 is withdrawnfrom the opening 9 in the shuttle, as shown in Fig. 2, and as theshuttle is boxed it stops with said opening in alinement with theopening 8 in As the lay beats up and the feeler strikes the buffer 22 itis thrown from the full-line into the dotted-line position, the end 7thereof being moved into the recess 9 in the shuttle. When, however, afloat occurs, the feeler controller is released, as above described. andis'moved across the recess 9 by the action of the spring 19. When thelay makes the next forward movement and the feeler strikes the buffer22, said feeler is prevented by its contact with the feelercontrollerfrom swinging into the dotted-line position, and therefore becomes arigid hunter, and as it strikes the buffer it forces the lever 20 back,and thereby knocks the shipper off,

thus stopping the loom.

The buffer 22 is preferably yieldingly mounted, and its operative faceis inclined, as shown. so that when the feeler is held by thefeeler-controller in its operative position it will strike the thickerportion of the buffer.

\Yhile my improvements can be applied to any type of loom and can beused in connection with any type of shuttle, I have herein illustratedan ordinary spindle-shuttle. 'ith suitable modifications, however, theinvention can be applied to shuttles commonly used on looms in which thefilling is automatically replenished when exhausted.

The particular form of knock-off device for the shipper-lever is notessential to my invention, and the arm 20 may be connected to any of theknock-off devices commonly employed in looms without in any waydeparting from my invention. It will be obvious, therefore, that manychanges in the construction and arrangement of parts may be made withoutavoiding the invention.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. In a loom, a shuttle, loom-stopping mechanism including a feeler, andmeans carried by the shuttle and cooperating with said feeler to stopthe loom upon the occurrence ofa float in the warp.

2. Ina loom, ashuttle,.loom-stopping mechanism including a feeler, afeeler-controller carried by the shuttle and cooperating with saidfeeler to stop the loom upon the occurrence of a float in the warp.

3. In a loom, ashuttle havingarecess, loomstopping mechanism comprisinga feeler, means to move said feeler into and out of the recess in theshuttle by or through the movement of the lay, and means cooperatingwith the feeler to stop the loom upon the occurrence of a float in thewarp.

I. In a loom, a shuttle having a recess, a feeler, means to move saidfeeler into said recess upon the forward movement of the lay, afeeler-controllcr, means to move the latter into its operative positionacross said recess and into the path of the feeler whenever a floatoccurs in the warp, and means cooperatin the warp, saidfeeler-controller when opoted to the lay, means to roclrsaid fecler' byor through the movement of the lay, a normally inoperativefeeler-controller carried by the shuttle, and means to render saidcontroller operative upon the occurrence of a float in the warp, saidcontroller when operative cooperating with the feeler to stop the loom.

7. In a loom, a shuttle provided with a recess, a feeler pivoted to thelay, a feelcr-controller, a float-detecting lever to hold said feelernormally inoperative, automaticallyoperativc means to throw thefeeler-controller into operative position when the latter is released,and means cooperating with said feeler to stop the .loom when thefeeler-controller is in its operative position.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
